The kids beg, the mum negotiates, and dad sits at the head of the table delivering an absolute "NO." "Absolutely not. No pets. End of discussion." He means it. And then six weeks later, he is baby-talking to a golden retriever named Captain Biscuit.
The thing about dads and pets is that the resistance is futile. The louder the initial "no," the more likely you are to find that same dad three months later lying on the floor letting the cat walk on his face. Dads, we love you, and your pets clearly love you too, even if you will never fully admit it.
